<b>Objet :</b> [Gmsh] Help understanding MSH file entries while using "Periodic surface with translate "<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal" style="margin-bottom:12.0pt"><span lang="EN-US"> </span>Hi there,<br>
I am meshing a geometry with periodic (translated meshes) boundary conditions along one of the directions (X in my case). I am using<br>
periodic surface with translate to setup the translated periodic meshes. I need help understanding some entries in the Msh file generated specifically the section under "$Periodic" (See attached image, in my case surfaces 1 and 8 are periodic). I understand
that in my case their are totally 11 periodic entities -- 5 points , 5 lines and 1 surface and my trouble is in understanding the format of the output corresponding to each of these periodic entities. It will be of great help if some one explain to me what
is the format for each of these entities so that I can write a code to read the msh file and generate relevant input files for my finite element solver. I have attached the geo and mesh file.<br>
<br>
Thanks again<br>
